Remove the nose dependency and fix HMAC tests for Python 3.8 and newer.
Replace nose.tools.assert_equal() with unittest.TestCase.assertEqual()
in endpoint tests.
Specify MD5 explicitly as the HMAC digest algorithm, since hmac.new()
requires the digestmod argument starting with Python 3.8. Preserve
the original test behavior by using the historical MD5 default.
